The physical properties of the prepared porphyrin-TiO2 samples were investigated by several techniques such as X-ray powder diffractrometry (XRD), Scanning electron microscopy (SEM), Fourier-tranformed infrared
spectrophotometry (FT-IR), and UV-Vis diffused reflectance spectroscopy (DRS). XRD results showed the anatase phase was found in all samples. The DRS spectra revealed the modified porphyrin exhibited higher red shifts compared with unmodified-TiO2 sample The photocatalytic activity was evaluated via Orange II dye degradation under visible irradiation. The photocatalytic results revealed that most porphyrin modified TiO2 gave higher photocatalytic efficiency than the unmodified-TiO2 sample. 1. คานา (Introduction)
